ruby-jq
Ruby bindings for jq.
see http://stedolan.github.io/jq/.
Prerequisites
jq requires the Oniguruma library to provide regex support. To install Oniguruma for your system, please follow the instructions in the jq FAQ.
Installation
Add this line to your application's Gemfile:
gem 'ruby-jq'
And then execute:
$ bundle
Or install it yourself as:
$ gem install ruby-jq
Using system libraries
By default, ruby-jq downloads and compiles its own version of libjq. If you
would like to use your own version of libjq, you can skip this process by
passing the --use-system-libraries flag to gem install, or by setting the
RUBYJQ_USE_SYSTEM_LIBRARIES env var.
Usage
require 'jq'
src = <<EOS
[
"FOO",
{
"BAR": [100, 200]
},
1.23,
[1, "2", 3]
]
EOS
jq = JQ(src)
jq.search('.[]') do |value|
p value
# => "FOO"
# => {"BAR"=>[100, 200]}
# => 1.23
# => [1, "2", 3]
end
p jq.search('.[]')
# => ["FOO", {"BAR"=>[100, 200]}, 1.23, [1, "2", 3]]
jq = JQ(src, parse_json: false)
jq.search('.[1].BAR') do |value|
p value
# => "[100,200]"
